Module consts 

DExtra wire-format constants.

Every magic byte and every duration here is annotated with the exact line in the GPL reference implementation it was derived from.

Constants

CONNECT_ACK_TAG

ACK tag at offsets [10..13] of a 14-byte connect reply, followed by 0x00 at byte [13].

CONNECT_LEN

Connect (LINK/UNLINK) packet length (11 bytes).

CONNECT_NAK_TAG

NAK tag at offsets [10..13] of a 14-byte connect reply, followed by 0x00 at byte [13].

CONNECT_REPLY_LEN

Connect reply length (14 bytes: 11 + 3 tag).

CONNECT_RETX

Number of times the connect packet is retransmitted.

DEFAULT_PORT

Default UDP port for DExtra reflectors.

DISCONNECT_TIMEOUT

DExtra disconnect ACK timeout — give up waiting for unlink reply.

DSVT_MAGIC

DSVT magic at offsets [0..4] of every DExtra voice packet.

HEADER_RETX

Number of times the voice header is retransmitted.

KEEPALIVE_INACTIVITY_TIMEOUT

DExtra keepalive inactivity timeout.

KEEPALIVE_INTERVAL

DExtra keepalive interval.

POLL_LEN

Poll packet length (9 bytes).

VOICE_DATA_LEN

Voice data length (27 bytes).

VOICE_EOT_LEN

Voice EOT length (27 bytes, same as data but seq has 0x40 bit).

VOICE_HEADER_LEN

Voice header length (56 bytes).

VOICE_INACTIVITY_TIMEOUT

DExtra voice inactivity timeout — synthesize VoiceEnd after this.
